Stage One: Autolysis

The first stage of human decomposition is called autolysis, or self-digestion, and begins immediately after death. As soon as blood circulation and respiration stop, the body has no way of getting oxygen or removing wastes. Excess carbon dioxide causes an acidic environment, causing membranes in cells to rupture. The membranes release enzymes that begin eating the cells from the inside out.

Rigor mortis causes muscle stiffening. Small blisters filled with nutrient-rich fluid begin appearing on internal organs and the skin’s surface. The body will appear to have a sheen due to ruptured blisters, and the skin’s top layer will begin to loosen.

Stage Two: Bloat

Leaked enzymes from the first stage begin producing many gases. The sulfur-containing compounds that the bacteria release also cause skin discoloration. Due to the gases, the human body can double in size. In addition, insect activity can be present.

The microorganisms and bacteria produce extremely unpleasant odors called putrefaction. These odors often alert others that a person has died, and can linger long after a body has been removed.

Stage Three: Active Decay

Fluids released through orifices indicate the beginning of active decay. Organs, muscles, and skin become liquefied. When all of the body’s soft tissue decomposes, hair, bones, cartilage, and other byproducts of decay remain. The cadaver loses the most mass during this stage.

Stage Four: Skeletonization

Because the skeleton has a decomposition rate based on the loss of organic (collagen) and inorganic components, there is no set timeframe when skeletonization occurs.

Charlie runs a book rental business. He currently charges $3 per book and rents out an average of 38 books a day.

According to a study, for every 50¢ increase in rental price, the average business can expect to lose 4 rentals a day.

Complete the equation that models this scenario, where b(x) is the revenue generated and x is the number of 50¢ price increases.

b(x) = -____x2 + ____x + _____

Answers

Answer:

b(x) = -2x² + 7x + 114

Step-by-step explanation:

Step-by-step explanation:

First we convert 50 cent into dollar,

1 cent = dollar

1 cent = 0.01 dollar

50 cent = 0.5 dollar

According to question,

x is the number of 50¢=$0.5 price increases.

b(x) is the revenue generated

He currently charges $3 per book.

i.e. price of book = 3+0.5x

Quantity or average = 38 per day

According to a study, for every 50¢ increase in rental price, the average business can expect to lose 4 rentals a day.

i.e. quantity became 38-4x

Revenue = Price × Quantity

A triangle has sides represented by 7, x, and x−1. If the perimeter is 28, find the length of the longest side.

Answers

Answer:

x (11 unit) is the longest side

Step-by-step explanation:

Given:

Sides;

7, x, and x−1

Perimeter = 28

Find:

Longest side

Computation:

Perimeter = sum of all sides

So,

7 + x + (x -1) = 28

2x + 6 = 28

x = 11

So,

x -1 = 11 - 1 = 10 unit

x (11 unit) is the longest side

R

Answers

Answer:

18°

Step-by-step explanation:

Find the diagram attached

From the diagram, since the opposite side are parallel, the sum of the adjacent angle is 180 degrees

From the diagram, m<RQP + m<QPO = 180

Given

m<RQP = 6x+9

m<QPO = 63

Substitute

6x+9+63 = 180

6x + 72 = 180

6x = 180 - 72

6x = 108

x = 108/6

x = 18 degrees

Hence the value of x is 18°

Which associations best describe the scatter plot?

Select each correct answer.


Positive association

Linear association

Negative association

Nonlinear association

Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Time, in years. The vertical axis is labeled Number infected. Points are plotted at (one, one hundred), (two, ninety), (three, seventy-five), (four, sixty), (five, forty-five), (six, twenty-five), (seven, fifteen), (eight, five), (nine, zero).

Answers

Answer: Here you go hope this helps

If a line is drawn through (twenty, seventy) and (twenty-five, sixty), then you can use the points in getting the equation.

Slope is = (60-70)/(25-20) = -2

Using the two-point slope form, y – y1 = m(x – x1)

               y – 70 = -2(x – 20)

               y – 70 = -2x + 40

               y = -2x + 110

Step-by-step explanation:

The associate that best describes the scatter plot is the Negative association.

What is an associate?

An associate in a scatter plot tells us the relation between the two variables. There are 4 types of associates:

Positive associate: If the value of one variable is increasing the value of another increase as well, but the relation is not linear.

Negative associate: If the value of one variable is decreasing with the value of another increasing as well, but the relation is not linear.

Linear Associate: If the value of one is dependent on the other such that they follow a function of line, and all the data points are on that function line or near to it.

Non-linear Associate: If the data points of the plot are scattered and random, such that there is no relationship between the points.

If we plot the graph of the data points we will see that the trend of the data is negative, therefore, the value of one variable is decreasing with an increase in the value of another.

Hence, the associate that best describes the scatter plot is the Negative association.

Answer:

ST=8.8

SR=15.5

Step-by-step explanation:

ST is the difference between S and T.

that would be 16.3-7.5=8.8

similarly RT is the difference between S and R

That would be 7.5-(-8)=15.5.

Answer:

ST = 8.8

SR = 15.5

Step-by-step explanation:

As the question demonstrates, they're looking for the measure of ST - which means the distance from S to T.

Now to get ST you'll have to subtract the values given on the number line.

T = 16.3

S = 7.5

16.3 - 7.5 = 8.8

ST = 8.8

Moving on with SR, we have the following. We use the same method of differentiation.

S = 7.5

R = -8

7.5 - (-8) = 15.5

SR = 15.5
